(1) GPS_observations.dat

velocities in mm/yr. References provided at bottom of file.  These are the 
original observations in frames provided by authors or provided in 
publication form.


(2) GPS_rotated.dat

These are the observations that have been rotated into a model Eurasia frame
of reference.  The rotation vectors, plus full covariance matrices, applied to 
each study to rotate into a best fit model Eurasia frame of reference are 
supplied in a table (Table1.ps). Velocities in mm/yr.


(3) model_v_GPS.dat

These are the velocities predicted by the model at the GPS sites.  These are in
a model Eurasian frame of reference. The model velocity field has been fitted
to the GPS vectors that have been rotated into the optimal frame of reference.
These GPS vectors are presented in GPS_rotated.dat. Velocities in mm/yr.


(4) velocity_model

These are the model velocities on a regular grid with grid spacing in lat 
and long of 2 degrees.  This velocity field is plotted in Figure 2b of 
Holt et al. [2000].
